2 45 the device of Patented Mar. 8, 1932 NITE MAX IE. enossnn, or snatrrrtn} ASHINGTON f i SPRINKLER Application filed July 1, 1929. Serial No. "375,054;

My present invention relates to an im-' proved sprinkler or distributing nozzle, which while adapted for various uses, is par ticularly designed for use with lawn and garden hose for watering flowers, plants, vegetables &c. The primary object of the invention is the provision of a device of this character that may be manipulated with facility, or may be setin place on the lawn,

w for sprinkling or watering the vegetation, and one of the essential accomplishments of the device is its ability to distribute the water in a multiplicity of small streams so that delicate flowers, plants &c. may be watered without subjecting sure or to dense volume of water, which would otherwise damage the plants and wash away the soil from the roots of the'plants. y

The inventionconsists'in certain novel combinations and arrangements'of parts in the structure of the sprinkler involving its chambered sprinkling or distributing head and the valve control therefor, as will hereinafter be more fully set forth and claimed;

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein the arts are combined and arranged according to the best mode I have thus far devised for the practical application of the principles of my invention.

Figure 1 is a view in side elevation of the sprinkler involving my invention. Figure 2 is a longitudinal sectional View with the distributing head broken away for convenience of illustration. Figure 3 is a transverse sectional view at line 3-3 of Figure 2. Figure 4 is a transverse sectional view at line H.016 Figure 3, and Figure 5 is a face view In Figures 1 and 2 I have shown the sprinkler as attached to the end of a garden hose 1 by means pling nut 3, and it will be understood that my invention isadapted for use with the standard hose and hose coupling. I

The sprinkler head 4 is of cylindrical shape and of suitable diameter and length for the purpose, and the front end ofthe' hollow head which forms a distributing chamber, is closed let pipe head as shown.

them to high water pres-' grooves 14 r plates to prevent leakage.

between the plates, of the usual nipple 2 and the cou-' by a screw cap '5 threaded on the end of the cylindera The' sprinkler headis provided with one or vmore longitudinallyextending rows of outlet portsf6 in its wall, through which the water is distributed-in numerous "fine streams,laterally of the head, and an in- 7 is providedkatfone end of: the head, being oftset'from the center of the v Thewater is thus introduced 'intoithedistributing chamber within the head under normal' pressure from .the' hose,-and a sufficient head of. water isprovided to force said pipe the em streams through the'ports '6' in order thatthe water may be showered by manipulating the sprinkler atthe end offthe hose.

Gr the'sprin'kler may be seton the lawn with V therow of ports in position to send out the sprayin the form: ofafountain so that the streams will rise and thenfall to the ground for watering purposes. i

7 jandthe sprinkling Between the inlet pipe heador'distributingchamber, a valve casing is interposed ;said casing comprising a plate 8 that. is welded tothe open end of the sprinkler head, and a complementary plate 9 that maybe welded to the inlet-pipe, said plates beingyjointedtogether,by means of bolts 10. The adjoining faces of the plates are"; provided with complementary edge flanges 11 that form betweenthe plates the valve chamberlEZ opening into the inlet/pipe through 13" and through port 13 to the distributing chamber or interior of the sprinklinghe'a-d. The inletport is made up of two circular openings 13 and 13 in the respec tive plates 8 and 9 and about these openings packing rings 14. are seated in annular in the adjoining faces of the A slide valve15 having a circular transverse port 16 is movable in the valve chamber course is adapted to register with 18 on the exterior end of the stem, the valve may be moved to vary the area of the valve port, and the walls of the valve chamber are provided with an opening 19 for the move--. ment of the stem; Y f It will be apparent. that the volume of was and the valveport of a the inlet port; By means of a stem 17 and the handle ter from the inlet pipe to the distributing chamber of the sprinkler head may be varied as desired, and that the Water is admitted to the distributing chamber remote from the outlet ports in order that turbulency of Water near the ports may be reduced for the purpose of enhancing the; distribution of the water through the outlet ports.

The device as thus described and shoWn is simple in both construction and operation, is durable and rugged and not likely to become deranged. From time to time the cap 5. may be removed for the purpose of gaining access to the interior of the sprinkler head and the outlet ports may be cleansed when necessary.

Having thus fully described my invention, What I claim as new and desireto secure by Letters Patent is '1. A sprinkling device consisting of an inlet pipe;"a' sprinkler head of much greater cross-sectional area than theinlet pipe; the axis of the said inlet pipe being ofisetfrom the axis of the sprinkler head placing the pipe at the uppermost point of the sprinkler head; a slide valve, disposed between said inlet pipe and the sprinkler head, so arranged that thevalve opening is at the uppermost point of the sprinkler head; and a plurality of outlet ports disposed remotely from the axis of the inlet pipe.

2'. A sprinkling device consisting of an in- 7 let pipe; a sprinkler head of much greater cross-sectional area than the inlet pipe; the

axis of the said inlet pipe beingoffset from the axis of the sprinkler head placing the pipe at-the uppermost pointof the sprinkler head; a-portedend plate for said sprinkler head; a portedend plate-on said inlet pipe; said ported end plates being recessed to pro vide a slidevvay for a valve member and further having annular grooves around their ports which are adapted to secure packing rings; in place; a ported slide valve disposed Within said slid'eWay and adapted to close when in its uppermost position; and a plurality e-fi outlet ports disposed remotely from the aXis of the inlet pipe.

In testimony whereof I affix my signature MAX F. GROSSER.
